This at least confirms that you have a single monitoring chip on your
board, a Winbond W83627HF (as advertised by Tyan).

Sensors-detect is broken here, it should NOT tell you to load the
w83781d driver. I'm not sure how we can fix that though. Both drivers
support your chip, but only one should be loaded at any given time. The
w83627hf driver is prefered in your case.

Remove i2c-i801 and w83781d from that list.

Of course, because the latter prevents accesses from the former.

Please edit your init files as required so as to only load the w83627hf
and i2c-isa drivers, then cold reboot your system. Not certain it'll
help for the temperatures but at least we will have a sane base to work
on.
